The aim of this multi-centre retrospective study was to clarify the prognostic factors for respiratory-related death in patients with interstitial lung disease (ILD) complicated rheumatoid arthritis (RA). Patient background data, treatment regimen, and disease activity indicators of RA and ILD at baseline, 6 months after the diagnosis of ILD, and at the last follow-up visit were extracted. A total of 312 patients with RA-ILD (17 patients who died from respiratory-related causes and 295 survivors) were included. Patients who died from respiratory-related causes had an older median age, a higher proportion of being male, and a higher anti-cyclic citrullinated peptide antibody positivity rate than survivors (p =.0001, .038, and .016, respectively); they also had significantly higher baseline serum levels of Krebs von den Lungen-6 (KL-6) than survivors (p =.013). Patients who died from respiratory-related causes showed significantly greater changes in serum KL-6 levels between the 6-month time point and the last visit [ΔKL-6 (6 months - last)] than survivors (p =.011). Multivariate analysis showed that the ΔKL-6 (6 months - last) corrected by disease duration was a predictor of respiratory-disease-related death in patients with RA-ILD (p < .0001). Long-term increase in serum KL-6 levels is associated with respiratory-disease related death in patients with RA-ILD. [ABSTRACT FROM AUTHOR]

Objectives To elucidate the serum cytokine profile and address the pathomechanism of interstitial lung disease (ILD) complicated with PM/DM. Methods Forty patients with PM/DM-ILD were enrolled, and principal components analysis and cluster analysis were performed to classify patients into subgroups. Additionally, we compared cytokine profiles between the survivors and dead patients and between anti-melanoma differentiation-associated gene 5 antibody- and anti-aminoacyl tRNA synthetase antibody-positive ILD patients. We also examined the association of various cytokines with disease activity indicators and prognosis of ILD. Results The principal components analysis data allowed classification of the cytokine profile into three groups: group 1, neutrophilic and M1-macrophage-driven cytokines; group 2, type 1 Th cell-driven and M2-macrophage-induced cytokines; and group 3, M2-macrophage-driven cytokines. Cluster analysis showed the presence of PM/DM-ILD patient groups with high or low levels of total cytokines. Ninety percent of patients who died of ILD were included in clusters with high cytokine levels. Serum cytokine levels of all groups were significantly higher in the anti-melanoma differentiation-associated gene 5 antibody-positive patients than in the anti-aminoacyl tRNA synthetase antibody-positive patients. Groups 1 and 2 significantly correlated with known factors for poor prognosis, such as serum ferritin levels and alveolar-arterial oxygen difference. Serum cytokine levels of patients in group 1 were significantly higher initially and at 2 and 4 weeks in those who died. Conclusion These findings suggested that the activation of monocytes, macrophages and type 1 Th cells, and neutrophils play roles in the pathomechanism of PM/DM-ILD, and group 1 cytokines could be useful biomarkers for predicting prognosis of PM/DM-ILD.

Background: Achieving aesthetic results with forehead augmentation procedures remains challenging. We have developed a method of integrated forehead and temporal augmentation using a three-dimensional (3D) printing-assisted methyl methacrylate implant.Objectives: The study objective was to assess the importance of combined temporal augmentation when performing forehead augmentation.Methods: We identified 34 patients (from 2000 to 2010) who underwent forehead augmentation with a methyl methacrylate implant contoured in situ during surgery and 41 patients (from 2010 to 2016) who underwent integrated forehead and temporal augmentation with a prefabricated methyl methacrylate implant. We conducted a retrospective chart review of patient data including operation time, complications, and instances of revision surgery. Two blinded plastic surgeons scored the aesthetic results of the operations on a 4-point scale (1, poor, to 4, excellent) based on preoperative and posttreatment photographs.Results: The integrated augmentation method resulted in a lower frequency of posttreatment implant removal (one [2%] vs. six [18%]; P < .05), a lower frequency of filler injection for touch up (one [2%] vs. six [18%]; P < .05), and higher mean aesthetic scores (3.7 ± 0.5 vs. 2.2 ± 1.0; P < . 001) compared to the forehead augmentation method. There was no statistically significant difference in surgical complications between the two groups.Conclusions: Integrated forehead and temporal augmentation using a 3D printing-assisted methyl methacrylate implant may be the optimal available procedure, enabling the custom fabrication of contours requested by the patient and providing a rejuvenating and balancing effect on facial appearance.Level Of Evidence3: [ABSTRACT FROM AUTHOR]

The prognosis of dermatomyositis (DM)-associated progressive interstitial pneumonia (IP) has recently been improved by steroids/cyclosporine-A (CSA) combination therapy, but treatment outcomes varied. One reason for this variation is thought to be differences in CSA regimen. There is marked interpatient variability in CSA absorption. However, the pharmacokinetics of CSA has rarely been studied. In this study, we calculated the area under the blood concentration-time curve (AUC) of CSA microemulsion in 15 patients with progressive IP complicating DM, and analyzed its correlation with CSA levels at blood sampling time points to investigate the optimum monitoring and dosing regimen. The highest correlation between AUC and blood level of CSA was observed 2 h (C2) after drug administration ( R = 0.910). The trough level (C0) was not correlated with AUC ( R = 0.052). There were no differences in blood levels (AUC, C2, and C6) between postprandial administration in a divided dose (CSA given twice daily) and preprandial administration once daily in a single dose, while C0 was significantly lower ( P = 0.020) when the drug was administered once daily before breakfast. These findings suggest that measurement of CSA blood level, especially C2 and C0, is useful to monitor clinical and adverse effects of CSA during combination therapy. It is also suggested that preprandial, once daily administration of CSA is beneficial in DM patients with progressive IP. [ABSTRACT FROM AUTHOR]

Thrombotic thrombocytopenic purpura (TTP) is in rare cases associated with antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, and often has a fatal outcome. We report the case of a 77-year-old woman with microscopic polyangitis (MPA) presenting with TTP. Rapidly progressive renal dysfunction and paralysis and sensory disturbance of the left lower limb were noted. Serum creatinine was 3.95 mg/dl, and the titer of myeloperoxidase-ANCA was 238 EU. She was diagnosed with MPA, and high-dose methylprednisolone was initiated, followed by 60 mg/day of prednisolone. Hemolytic anemia with red blood cell fragmentation, purpura, and thrombocytopenia developed during the course of active MPA. The activity of disintegrin and metalloproteinase with thrombospondin type 1 motifs 13 (ADAMTS13) was moderately decreased (27%). She was diagnosed with TTP, and plasma infusion was initiated, followed by plasma exchange (PE) with 40 units of fresh frozen plasma. Thrombocytopenia continued for more than a month (5–10 × 104/μl). PE was repeatedly performed two or three times a week during the first 8 weeks from the beginning of PE in addition to prednisolone. Her clinical and laboratory findings gradually improved, and ADAMTS13 activity increased to 68%. The findings in this case suggested that ANCA-associated vasculitis may be involved in the development and the pathogenesis of TTP, and that repeated PE may need to be performed in addition to immunosuppressive therapy.
